Thanks Mark, and Bager. You confirm what is so obvious from the picture I received. It is just not realistic. Yesterday I went to the Australian archive site, but it was closed for repair! My friend in Sharjah tells me that the fuel cans are indeed food oil cans, of which there are still a number in the museum at ex-RAF Sharjah. In fact I remember seeing them there.
PS: the nla site is now back on-line.
